Operation steps are as follows:
(1) Turn off the power.
(2) Turn off the cold-water inlet valve, and then turn on the hot-water faucet (as the below
picture shows).
(3) Connect the drain mouth to an appropriate outfall with a hose, (The minimum durable
temperature of the host should not be lower than 80ºC, if the host does not meet these
requirements, please open the cold-water inlet valve and the hot-water outlet faucet until the
water is not hot).
(4) Open the water outlet and drain all the tank water out. If needed, clean the inner tank
several times to remove all sediment (it depends on the cleanliness of the water outlet).
(5) Turn off the water outlet, then refill the tank and reconnect to the power.
5. Please check regularly whether the unit’s power supply and the wiring of electrical systems
are firm or not, whether the electrical components have any abnormal phenomenon or not.
If yes, please ask your local dealer or contact us to replace and repair the machine.
6. Please check whether the safety valve of water system is working properly or not, so as not
to affect the unit’s heating capacity and the reliability of the unit’s operation.
7. If you shut down the heat pump for a long time, please remove the water of pipes system and
the tank, then cut off the power and put a protection cover. Before re-operating the machine,
please conduct a comprehensive examination of the system first, fill with water and then
restart the machine.
8. Each water heater is equipped with an anode rod to protect the water tank from corrosion,
but the anode rod will also be corroded slowly. The corrosion rate depends on the local water
quality. We recommend that you check the anode rod every six months and change a new
one if the anode rod runs out. Please contact the dealer or special technical center about
detailed information.
